Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Unedited at normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

Well, isn't this a surprise! A tranquil #Triggerfish lounging about. Known for their fierce territorial nature, these #seacreatures are infamous for their feisty 'keep-off-my-lawn' attitude. Intruders beware, as they won't hesitate to escort you out, including #snorkelers and #divers. And if they feel they are under threat, brace yourself for a spirited encounter! But it looks like our diver friend here stumbled upon a laid-back Triggerfish taking a siesta. So are you up for some underwater intrigue and possibly bumping into these spirited little #fish #undersea? Grab your gear and come dive with us on a #liveaboarddivingtrip this month in #KomodoNationalPark. Just remember, if you meet them, respect their space and let the adventure unfold! ✉️ info@LaGaligoLiveaboard.com 💬 +62 812 2000 2025 (WhatsApp) 🌐 www.LaGaligoLiveaboard.com 🌐 Trip.LaGaligoLiveaboard.com (Schedule & Rates) ~~~~ #scubadiving #scuba #diving #diver #liveaboard #liveaboardIndonesia

When you lock in and accelerate, limits disappear. ⚡️🏁 . Meet the Manta 2026: the board built for riders who crave raw acceleration, speed, and total confidence at full power. From glassy speed strips to rolling ocean chop, the Manta turns every gust into forward drive and every reach into a chance to hit new top speeds. . Smaller sizes race through strong-wind speed runs with precision and control, while larger Mantas deliver powerful lift, early planing, and unmatched efficiency on demanding slalom tracks. Whatever the course — long reaches, technical gybes, tight marks, or pure speed missions — the Manta stays balanced, fast, and ready to dash ahead. Discover your go-to weapon for dominating the course and crossing the finish line first: 🌐 https://tabou-boards.com/boards/manta/ #tabouwindsurfing #tabouboards #notjustbetterdifferent #windsurfing #slalom #racing
